2668-AA_2018_Energy_Forms2018 Washington State Energy Code — Residential Prescriptive Ener Cod Co liance for All C€€mate Zones €n Washington Single Farriily�Additions (effective February t, 2021) Version 1,0 These requirements apply to all IRC building types, including detached one- and two-family dwellings and multiple single-family dwellings (townhouses). l Contact Information 26WAA ICE DEVELQPMENT Instructions: This single-family project will use the requirements of the Prescriptive Path below and incorporate the minimum values listed. Based on the size of the structure, the appropriate number of additional credits are checked as chosen by the permit applicant. Provide all information from the following tables as building permit drawings: Table 8402.1- Insulation and Fenestration Requirements by Component, Table 8405.2 - Fuel Normalization Credits and 40G.3 - Energy Credits.

When Insulation is installed in a cavity that is less a than the label or design thickness of the insulation, the compressed R -value of the Insulation from Appendix Table A101.4 shall not be less than the R-valuespecified in the table. b The fenestration U -factor column excludes skylights. "10/15/21 +STB" means R-10 continuous insulation on the exterior of the wall, or R-15 continuous insulation on the interior of the wall, or R-21 cavity insuIat€on plus a thermal break between the slab and the basement wall at c the interior of the basement watt. "10/15/21 +STB" shall be permitted to be met with R-13 cavity Insulation on the interior of the basement wall plus R-5 continuous insulation on the interior or exterior of the wall. "518" means R-5 thermal break between floor slab and basement wall. d R-10 continuous insulation is required under heated slab on grade floors. See Section R402.2-9.1. For single rafter- or joist -vaulted ceilings, the insulatlon may be reduced to R-38 if the full insulation depth e extends over the top plate of the exterior wall. _ R-7.5 continuous insulation Installed over an existing slab is deemed to be equivalent to the required perimeter f slab insulation when applied to existing slabs complying with Section 8503.1.1. If foam plastic is used, it shall meet the requirements for thermal barriers protecting foam plastics. For log structures developed in compliance with Standard ICC 400, log wails shall meet the requirements for g climate zone 5 of ICC 400. Int. (intermediate framing) denotes framing and insulation as described in Section A303.2.2 including standard h framing 16 inches on center, 78% of the wall cavity insulated and headers Insulated with a minimum of R-10 insulation. Prescriptive Path — Single Fancily 2018 Washington State Energy Cade -R 2018 Washington State Energy Code - Residential Prescriptive Energy Code Compliance for All Climate Zones in Washington Single Family & Additions (effective February 1, 2021) Each dwelling unit in a residential building shall comply with sufficient options from Table 8406.2 (fuel normalization credits) and Table 406.3 (energy credits) to achieve the following minimum number of credits. To claim this credit, the building permit drawings shall specify the option selected and the maximum tested building air leakage, and show the qualifying ventilation system and its control sequence of operation. 1. Small Dwelling Unit: 3 credits Dwelling units less than 1,500 sf in conditioned floor area with less than 300 sf of fenestration area. Additions to existing building that are greater than 500 sf of heated floor area but less than 1,500 sf. 2. Medium Dwelling Unit: 6 credits All dwelling units that are not included in 41 or #3 3. Large Dwelling Unit: 7 credits Dwelling units exceeding 5,000 sf of conditioned floor area 4. Additions less than 500 square feet: 1.5 credits All other additions shall meet 1-3 above Before selecting your credits on this Summary table, review the details In Table 406.3 (Single Family), on page 4.
